Qualla: Welwyn Tunnel rail crash

Welwyn Tunnel rail crash: Introduction

Tue, 19 May 2026 00:00:00 GMT

Code for 'No': three beats. Code for 'Out': four beats. On the night of 9 June 1866, in a signal box at Welwyn on the Great Northern Railway, a signalman heard four beats clatter through the telegraph needle when his colleague at Knebworth, three miles up the line, swore afterwards he had sent three. That single click of misread iron sent the second of three trains chasing the first into the darkness of Welwyn North Tunnel, where the first had quietly stalled with a failed engine. The third arrived before anyone could shout a warning. The historian L T C Rolt called it 'from the point of view of damage to engines and rolling stock one of the most destructive in railway history' - though as so often in the early years of British railways, what burned in the dark was less interesting to investigators than what had to change in the daylight afterwards.

Wray and Rawlins were the only deaths - a smaller toll than the damage might suggest, though the destruction of locomotives and rolling stock was enormous. Captain F H Rich of the Royal Engineers conducted the inquiry. His report, in the careful prose of Victorian disaster invest...

Rich recommended two specific changes, and the industry adopted both. First, before any train could enter a section of line, the signalman in front had to be positively asked for, and positively grant, permission - rather than the loose 'out of section' system in which one acknow...
